Methylotrophic or methanotrophic bacteria such as Methylobacterium are transformed with a gene of interest, and expression of the gene is regulated by means of a cumate repressor protein and an operator sequence which is operatively linked to the gene of interest, and the addition of an external agent. Specifically, the cymR repressor and cmt operator from Pseudomonas putida may serve to regulate gene expression in methylotrophic or methanotrophic bacteria with the addition of cumate.

The invention discloses a strain of pseudomonas producing ferulic acid esterase and application thereof, belonging to the fields of fermentation engineering and biotechnology. The Pseudomonas oryzihabitans Y‑5 of the present invention was deposited in the China Center for Type Culture Collection on July 13, 2018, with the preservation number CCTCC NO: M 2018480. The strain can secrete ferulic acid esterase. Under the induction of bran, the ferulic acid esterase activity of the fermented crude enzyme solution is 116U / L, and ferulic acid is produced by fermentation with wheat bran as the substrate, and the yield can reach 59.51±0.6mg / L. The Pseudomonas of the present invention can increase the content of ferulic acid in the rice wine without affecting the alcohol content, pH value and reducing sugar content of the rice wine. The content of ferulic acid is about 2.6 times that of traditional wheat koji.

The present invention aims at providing a mucosal vaccine composition that can be administered to an intraoral mucous membrane, ocular mucous membrane, ear mucous membrane, genital mucous membrane, pharyngeal mucous membrane, respiratory tract mucous membrane, bronchial mucous membrane, pulmonary mucous membrane, gastric mucous membrane, enteric mucous membrane, or rectal mucous membrane, that is useful as a prophylactic or therapeutic agent for infectious diseases or cancers, and is capable of safely and effectively inducing the systemic immune response and mucosal immune response. The present invention provides a mucosal vaccine composition to be administered to at least one mucous membrane selected from the group consisting of a human or animal intraoral mucous membrane, ocular mucous membrane, ear mucous membrane, genital mucous membrane, pharyngeal mucous membrane, respiratory tract mucous membrane, bronchial mucous membrane, pulmonary mucous membrane, gastric mucous membrane, enteric mucous membrane, and rectal mucous membrane, containing: at least one antigen; and as an adjuvant, a lipopolysaccharide derived from at least one gram-negative bacterium selected from the group consisting of Serratia, Leclercia, Rahnella, Acidicaldus, Acidiphilium, Acidisphaera, Acidocella, Acidomonas, Asaia, Belnapia, Craurococcus, Gluconacetobacter, Gluconobacter, Kozakia, Leahibacter, Muricoccus, Neoasaia, Oleomonas, Paracraurococcus, Rhodopila, Roseococcus, Rubritepida, Saccharibacter, Stella, Swaminathania, Teichococcus, Zavarzinia, Pseudomonas, Achromobacter, Bacillus, Methanoculleus, Methanosarcina, Clostridium, Micrococcus, Flavobacterium, Pantoea, Acetobacter, Zymomonas, Xanthomonas, and Enterobacter, or a salt thereof.

A composition comprising a purified extract isolated from Pseudolysimachion rotundum var. subintegrum containing abundant amount of active ingredient or the compounds isolated therefrom as an active ingredient for treating a chronic obstructive pulmonary disease and the use thereof. Inventive purified extract and compounds showed potent anti-COPD activity without beta-2-receptor agonistic response through various in vivo tests as well as in vitro test. Therefore, it can be used as the therapeutics or functional health food for treating and preventing chronic obstructive pulmonary disease (COPD).

The invention relates to a kitchen garbage degrading composite microbial inoculum and a preparation method and application thereof. The kitchen garbage degrading composite microbial inoculum is prepared by mixing a mixed inoculum of bacillus amyloliquefaciens, radiation-resistant methylobacterium, dispersed pantoea, pseudomonas oryzihabitans, citrobacter freundii and staphylococcus cohnii and a carrier, wherein the mass of the mixed inoculum accounts for 15-25% of the total mass of the kitchen garbage-degrading composite microbial inoculum; the mass ratio of the bacillus amyloliquefaciens, the radiation-resistant methylobacterium, the dispersed pantoea, the pseudomonas oryzihabitans, the citrobacter freundii and the staphylococcus cohnii is (1.5-3):(1-1.5):(1-1.5): (1-1.5):(1-1.5):(1-1.5); the kitchen garbage-degrading composite microbial inoculum is used for degrading kitchen garbage. Compared with the prior art, the kitchen garbage degrading composite microbial inoculum has the advantages as follows: the kitchen garbage degrading composite microbial inoculum can effectively degrade common vegetables, grains, fish, poultry meat and other kitchen garbage, has the degradation rate being above 80%, is high in degradation speed rate and small in odor, does not produce pollutants or poisonous substances, and is low in cost and stable in performance.

The invention discloses a free living nitrogen fixing bacterium pseudomonas oryzihabitans MBC4. The preservation number of the free living nitrogen fixing bacterium pseudomonas oryzihabitans MBC4 is CGMCC No.10820, the preservation date is May 19, 2015, and the preservation institution is China General Microbiological Culture collection Center. The strain can still live, breed and have nitrogen fixation activity under drought, large temperature differences, salt and alkali disasters and strong ultraviolet radiation. A microbial agent prepared from the free living nitrogen fixing bacterium pseudomonas oryzihabitans MBC4 can be applied to ecological systems with drought, large temperature differences, salt and alkali disasters and strong ultraviolet radiation, can increase nitrogen accumulation in the ecological systems and can perform the function of improving soil environments and the physiological activity of microorganisms and plants and increasing net primary productivity.
